Product Description
P+F Fieldbus Barrier RD0-FB-Ex4
The FieldBarrier, a device coupler for DIN rail mounting, connects 4 instruments with intrinsic safety (Ex ia/Ex ib) and short circuit current limitation at each output. This ensures proper operation of the segment during faults or hot work at the spur.
High power on the trunk enables maximum cable lengths and device count in any hazardous area. The integrated fieldbus terminator features high-availability design and is selectable.
Output terminals with a choice of fixed or plug-in screw terminals connect 1 device each. LEDs simplify troubleshooting and help decrease repair time. Any grounding and shielding concept is possible based on FieldConnex® enclosure solutions.
